My weapon of choice as a stock picker is research; it’s critical for me to understand a company’s value before laying down a dime. I really had no choice in this matter, for when I first happened upon the writings of Benjamin Graham, I felt as if I was born to play the role of value investor. All my stock picking is 100% based on the concept of a margin of safety, as introduced to the world in the book "Security Analysis," which Graham co-authored with David Dodd. By now I have my own version of their techniques, but the net is that I want to protect my downside to prevent permanent loss of capital. Specific, known catalysts are not necessary. Sheer, outrageous value is enough.
